Ronald Curry interviewed for Saints Offensive Coordinator

St. Widge said
But, I would still prefer a new OC with a new system. Especially something in the Shanahan/McVay school because while all NFL offenses are complicated, I think that school of offense is easier to learn than most because of the limited formations, puts QBs in a better position to succeed with some easier throws, and several guys have succeeded in that system in year one, i.e. Stafford, Burrow, Purdy, Jake Browning. So, I have some confidence that Carr could break the pattern of learning a new offense in the right system.

In Shanahan's system, it's been observed that for some reason it can take QBs a year before they get truly comfortable (Matt Ryan comes to mind, but there may be others I can't think of at the moment).

But McVay's QBs tend to have immediate success in their first year (Goff, Stafford). So there are differences between the two systems (Shanahan's run concepts are particularly distinctive to his tree).
